"We are moving into an older house with asbestos covering on the pipes. A representative from JBH came in for an estimate and gave us a very accurate idea of the overall cost. Something that we were not able to confirm at the time of the removal...we were told this was a family-owned business and that someone from the family would come in to do the removal. Neither of the men who showed up introduced themselves as part of the family... The men from JBH showed up on time (very polite guys), removed all the asbestos, and then brought us down to show the work they had done. We were supposed to bring in an independent contractor for air monitoring, but the people we reached out to never returned our calls (they'll get their OWN review on Angie's List). In all the craziness of our move, we forgot that we never actually booked an air monitering company. We called JBH the day of the scheduled removal to let them know about the situation and to see if we should reschedule - they ended up calling someone in on our behalf to do the monitering. Not the ideal scenario, but it was great that they did the extra legwork with practically no notice. We did have to call JBH ourselves to follow up on the air testing results, which was the one downside."

"Mike is absolutely amazing. We wanted our basement air tested so we can safely work there and he did all the tests and advised us on a number of things that have indeed greatly improved the air quality. He also volunteered to take a look through our house and he identified mold in our bathroom that I hadn't even seen! He told us exactly what to do to get rid of it and it worked. I highly recommend Mike."

FAQs for radon gas testing projects in Harrison, NY

Radon is the second leading cause of lung cancer in the U.S. The gas seeps through cracks in foundations and collects in basements and other low areas. Once you breathe it in, radioactive particles lodge in lung tissue and do long-term damage. Because you can’t see or smell radon, the EPA recommends testing your home every two years—and after major renovations—to keep your family safe.

Yes—every home should be tested. The EPA advises doing it at least every two years and any time you remodel, buy, or sell. On average, one in 15 houses nationwide sits above the recommended limit, and the only way to know where yours stands is a formal test. The equipment simply measures gas levels and won’t change your indoor environment, so the process is completely harmless.

Certified radon professionals—often home inspectors or dedicated radon mitigation contractors—handle testing. These radon testing professionals follow EPA protocols and use calibrated instruments to check levels throughout your house. Hiring a certified radon specialist means results you can trust for real estate deals, insurance requirements, and, most importantly, your family’s health.

Inspectors specialize in measuring radon gas levels, while licensed mitigation contractors design and install the systems that remove it. If your test comes back high, your inspector can point you to a qualified mitigation pro who will size and install the right fan, piping, or other equipment to bring levels down.

No—standard home air purifiers don’t touch radon. They’re built to trap dust and pollen, not radioactive gas. If testing shows high levels, you’ll need a dedicated mitigation system that vents the gas from beneath your home to the outdoors. Relying on a room purifier alone won’t keep your indoor air safe.

Opening a few windows in your home might dilute radon for a short time, but the gas seeps back in as soon as they’re closed. For a lasting fix, you’ll need a professional mitigation system—often a sub-slab depressurization fan—that pulls radon from beneath the foundation and safely vents it outside.
